We studied anticipatory postural adjustments in patients with Parkinson's disease who dropped a load from extended arms while standing. Anticipatory postural adjustments were seen when load dropping was induced by a fast, bilateral shoulder abduction but not when it was induced by pressing a trigger with the right thumb. We conclude that anticipatory postural adjustments in patients with Parkinson's disease can change with the magnitude of an action which is used to trigger a predictable postural perturbation. Thus, the described deficits in anticipatory postural adjustments in patients with Parkinson's disease are likely to be of quantitative rather than qualitative nature.
我们研究了帕金森病患者在站立时从伸展的手臂放下重物时的预期姿势调整。当通过快速双侧肩部外展诱发重物放下时可观察到预期姿势调整，但当用右手拇指按压扳机诱发时则未观察到。我们得出结论，帕金森病患者的预期姿势调整会随着用于引发可预测姿势扰动的动作幅度而改变。因此，帕金森病患者中所描述的预期姿势调整缺陷可能是数量上而非质量上的。
